Default Data Applications
Used with 7500 and World Class BRI Data Modules. Used to identify mode to be 
Used with originating data calls when the mode is not specified with the calling 
parameters. This mode is also used for terminating trunk calls that do not have 
bearer capability specified or administered connections. Refer to ‘‘
Generalized 
route selection’’ on page 1351 for additional information.
MM Complex Voice Ext:
Used with 7500 and World Class BRI Data Modules. This display-only field 
contains the number of the associated phone in the multimedia complex. It only 
appears when the Multimedia field is 
y. This field is left blank until you enter the 
data module extension in MM Complex Data Ext field on the Station screen. Once 
you complete the field on the Station screen, these two extensions are associated 
as two parts of a one-number complex, which is the extension of the phone. Valid 
values conform to your dial plan.

Refer to ‘‘DLC Option Settings’’ on page 593 for additional information when 
assigning entries for the remaining fields on the screen.
KYBD Dialing
This option must be enabled to allow data endpoints to originate calls via the EIA 
232C interface and obtain ASCII feedback text. When enabled, the user gets the 
dial prompt. This option normally is enabled for “originate/receive” DTE that has 
a need to set up data calls. If this option is disabled, originations cannot be done at 
the DTE and text feedback does not occur at the DTE during call setup/take down. 
Data call answering is still allowed but without text feedback.
NOTE:
ADU-type hunt groups connecting the system to terminal servers on a host 
computer should have these hunt group extensions assigned as “no” 
keyboard dialing.
Configuration
Appears when the KYBD Dialing field is 
y. This option normally is enabled for 
“originate/receive” DTE such as non-intelligent terminals and disabled for 
intelligent devices such as computers. The KYBD Dialing field must be 
y with 
this option.
Valid entries Usage
y/n
Enter y to allow keyboard dialing. This enables the data 
endpoint to receive and transmit text during call origination or 
termination. Low must be 
n.
Valid entries Usage
y/n
Enter y to allow the viewing and changing of options from the 
DTE.

Busy Out
This option should be enabled for DTEs that are members of a hunt group and to 
allow “busy out” when DTE turns power off so that calls do not terminate on that 
DTE.
SPEEDS
Enter y to select operating speeds as follows:
Permit Mismatch
This option allows the EIA interface to operate at a rate different than that agreed 
to in the data module handshake. (The data module handshake is always the 
highest compatible rate as determined by the reported speed option of each data 
module.) Permit Mismatch eliminates the need to change the DTE/DLC speed 
every time a call is placed to/from an endpoint operating at a different speed. 
Valid entries Usage
y/n
Enter y to place the DLC port in a busied-out state once the DTE 
control lead to the DLC is dropped. 
Valid entries Usage
Low
Enter y to instruct the DLC to operate at a low speed from 0 to 
1800 bits per second (bps). Enter n if the KYBD Dialing field is 
y. 
300, 1200, 
2400, 4800, 
9600, or 
19200Enter y beside the desired operating speed. Enter n if the speed 
is not desired. The DLC can be any one of these speeds. The 
speed is matched for the duration of the call, from call setup to 
call takedown.
When multiple speeds are selected (select three or more, do not 
select just two speeds) and autoadjust is disabled, the DTE’s 
speed must be the highest selected speed. This is required 
because all feedback text is delivered to the DTE at the highest 
selected speed.
AutoadjustAppears when the KYBD Dialing field is y. Enter y which tells 
the DLC port to automatically adjust to the operating speed and 
parity of the DTE it is connected to. Enter n if this option is not 
desired. Autoadjust can be selected with any of the speeds 
selected in the previous step. Autoadjust allows the DLC port to 
determine the speed and parity of the DTE and then match itself 
to this speed. Autoadjust only applies to calls originated by the 
user through Keyboard Dialing.

When this option is enabled, the DLC reports the highest optioned speed and all 
the lower speeds (or the previously selected autoadjust speed) during the 
handshake process.
!CAUTION:
Caution must be used when using this option to send information from a 
DTE/DCE that is transmitting data at higher rates than that of the far end. 
Sustained usage of this type transmission results in loss of data. Whenever 
this option is enabled, the DTE must match the highest speed selected for the 
associated DLC port.
This option is intended to be used by a DTE device operating locally at a higher 
baud rate than that of its far-end connection but transmitting relatively low 
amounts of data (for example, a user typing at a terminal). Also, this option may 
be selected whether Keyboard Dialing is selected.
NOTE:
The Low speed setting is not reported as an available speed when the Permit 
Mismatch field is 
y.
Dial Echoing
Appears when the KYBD Dialing field is 
y.
Disconnect Sequence
Appears when the KYBD Dialing field is 
y. Selects the sequence for a disconnect.
Valid entries Usage
y/n
Enter y to instruct the DLC to operate at the highest selected 
speed, which is a higher rate than the far-end data module.
Valid entries Usage
y/n
Enter y to echo characters back to the DTE. Dial echoing should 
be disabled when keyboard dialing is done by an intelligent 
device.
Valid entries Usage
long-break
A long-break is greater than 2 seconds.

Answer Text
Appears when the KYBD Dialing field is 
y. This option enables text feedback that 
is normally delivered to the DTE when a call is answered or disconnected. The 
Answer Text option applies to DLC-generated text as well as text received from 
the system. If this option is disabled, the system still generates the text, but the 
DLC prevents it from being sent to the device.
This applies to the following messages:
— INCOMING CALL
— ANSWERED
— DISCONNECTED
— DISCONNECTED OTHER END
This option usually is disabled when the answering DTE is a computer or an 
intelligent device.
Parity
Appears when the KYBD Dialing field is 
y. Select the desired type of parity. The 
DLC generates the parities when call setup text is sent to the DTE. The DLC does 
not check the parity when receiving dialing characters. Parity has nothing to do 
with the far end; it is used by the DLC to terminal communications during call 
setup. Set to match the connected DTE.
Connected Indidation
Appears when the KYBD Dialing field is 
y. This option generates a 
“CONNECTED” message to the DTE when the connection has been established. 
If the KYBD Dialing field is 
n, the connected indication is provided by the DLC 
activating its EIA 232C control lead.

DLC Option Settings
The following provides additional information on the option settings for DLCs 
when used with the following types of devices:
nPrinters
nNon-intelligent terminals
nData terminals and personal computers
nHost computers
nInformation Systems Network (ISN)
Printers
A DLC port with a companion ADU, when attached to a printer, usually 
terminates a data call. Therefore, in this connection, the printer is the endpoint 
device. The originating device may be attached to a DCP mode 2 data module 
(such as the MPDM) or the DLC. A Z3A ADU extends the range of the EIA 232C 
connection.
When a receive-only printer (or any printer that does not generate the Transmit 
Data and DTR leads) is used, the ADU must be powered from a small 
plug-mounted transformer (2012D, or equivalent) connected to pins 7 and 8 of the 
modular jack. (Refer to ADU User Manual for details.)
An ADU cannot be used if the printer has hardware flow control using the Clear 
To Send (CTS) lead. An ADU can be used, however, if the printer is using 
software flow control.
A printer connected to a DLC is usually assigned as a line. Ta b l e  7
 lists the option 
settings for printer connections.

Data terminals and personal computers
An intelligent data terminal or a personal computer (PC) attached to a DLC can 
either originate or terminate a data call. A single ADU at the site of the originating 
device extends the distance signals can travel to the switch (the model ADU 
depends on the terminal connector). An analog telephone can be attached to this 
arrangement whenever an ADU uses the standard building wiring. Ta b l e  9

Host computers
A host computer may originate and terminate a data call. For this application, the 
number of DLCs required depends on the number of ports needed. An MADU can 
be used (instead of 8 ADUs) to complete the connection. Ta b l e  1 0

settings for a port that has a terminating connection to a host computer or an
